CSS | stroke-dasharray Property

Last Updated : 21 Nov, 2019

The stroke-dasharray property is used to set the pattern of dashes and gaps used in the stroke of SVG shapes. A larger value indicates a larger number of dashes. Different values can be specified in the array parameter to change the pattern.

Syntax:

stroke-dasharray: <dasharray> | none

Property Values:

dasharray: It is used to set the pattern with a list of values separated by commas or white space. The values can be both in terms of length units or percentages that specify the dashes and gaps in the pattern.
